Supply charges have no place in a 21st Century electricity network.
Do you know what I hate? What I truly despise? What causes black bile to bubble up from the deepest, darkest depths of my soul? Supply charges on electricity bills. [Read more…]

How To Find Solar Friendly Electricity Tariffs By Hacking Government Data
Learn how to hack the government’s electricity bill data for fun and profit…
If you own a solar system but haven’t shopped around the electricity retailers in a while, your bills are probably higher than they need to be.
The big gentailers, Origin, AGL and Energy Australia have made their disdain for solar very clear. They all lobbied to scrap government support for small scale solar during Tony Abbott’s RET review in 2014. And unsurprisingly their electricity tariff offers for solar owners are pretty ordinary.
Luckily there are lots of smaller retailers around these days that often beat the big names. And a handful of those offer solar Feed In Rates that are higher than the rates mandated by your state government. [Read more…]
RayGen combines solar technologies for bush solar revolution
The RayGen System focuses solar onto a novel concentrator. Image (c) Raygen
You get the best renewable energy stories tucked away in the rural press. Proof that solar power innovation in the bush is moving ahead by leaps and bounds. This despite the often backwards policy of our elected representatives.
So it was this week when a bit of digging unearthed the unveiling of a $3.6 million solar power facility in Newbridge in Central Victoria. The plant, developed by renewable research and development company RayGen Resources, combines PV cells with concentrating solar technology. [Read more…]
SA leads the way with 25 percent of households using solar: ABS
SA takes the medal for most solar systems per household.
The latest figures from the Australian Bureau of Statistics show one in five households use some form of solar energy. The figures back anecdotal and other statistical evidence of a massive growth surge for solar that has occurred since the ABS first began publishing statistics on solar energy, back in 2011.
Then the figures were comparatively low with only around five percent of households using solar energy, said the ABS’ Karen Connaughton in a 3/12/2014 press release. However the change in just three years has been dramatic.
“Jump just three years, to 2014, and there are solar panels being used by fourteen per cent of all households.”, she said.
Add to this solar hot water and the numbers of households using solar energy in one form or another has jumped to 20 percent. [Read more…]
Coal vs Solar – Which is more space efficient?
This is a guest post by Greg Bell – which was conceived in the comments section of another post on this blog.
Take it away Greg:
——-
Some things we can say we know for sure about photovoltaics – the fuel is free, it’s quiet, and there are no moving parts. But other benefits are more controversial. Recently a claim was made to me that solar PV is actually more area efficient – that is, it generates more energy per hectare – than coal.
Specifically, the claim was
“The 1,600 megawatt brown coal Hazelwood Power Station and associated mine in Victoria covers 3,554 hectares. In a sunny location in Australia 20% efficient solar panels covering that area would produce more kilowatt-hours than Hazelwood’s average output.”
Let’s see if that’s true. [Read more…]
Are micro inverters & battery backup compatible?
Can you combine micro inverters with batteries? Yes you can!
Can you use a micro inverter off grid? Or even for grid connect with batteries?
With the growth in the use of micro inverters, I’m starting to get more and more emails asking: can micro inverters be used in off grid (or hybrid) solar power systems? [Read more…]
Nine in ten look to solar to beat rising electricity bills: report
Rising electricity costs are driving more people to consider solar.
An Ernst and Young utilities survey report released this week has highlighted the battle ordinary Australians are having with their rising electricity bills. The study also found over 90 percent of those surveyed would like to switch to solar power. [Read more…]
Is midday the new off peak – thanks to solar?
Pylons carrying electricity at $0.005 per kWh. Last Saturday.
I was at home on a cloudy Saturday morning in Adelaide last week, performing some much needed repairs on my puppets in between refreshing my knowledge of chemistry. (Apparently everything is still made of atoms.) Then I noticed through a crack in the wall that the sun had come out and I opened the electrically operated steel shutters to see that, although there were still patches of cloud around, most of Adelaide was bathed in glorious noon sunshine.
On a whim I decided to check what effect this break in the weather had on grid demand and so I went to the Australian Electricity Market Operator’s site. Fortunately I could do this via internet and so didn’t have far to walk. I saw there had been quite a steep decline in demand which apparently had gone hand in hand with the clearing skies.

Solar lighting: Mandarin 2 adds style to practicality
The Victorian Premier’s Design Awards are currently being judged. Not your usual port of call for this correspondent I hear you say but bear with me readers! That’s because one of the many excellent designs under consideration is the Mandarin 2 solar-charged light which is flying the flag for solar lighting under the category “product design”.
Described on the Design Awards site as a “simple” design that “works” under the toughest of conditions, the Mandarin 2, as its name implies, offers a robust solar lighting alternative to more expensive and polluting energy sources such as kerosene. The handheld solar charged light is described as durable and reliable and ticks that important box for SQ readers — powered by renewable source — solar. [Read more…]
Does Mildura CPV solar farm offer a glimpse of the future?
Pretty dishy solar farm technology! Pic: Solar Systems P/L
Always great to bring our readers news of an Aussie breakthrough. However this week’s opening of Silex Systems’ massive CPV solar farm in Mildura, Victoria may prove to be more than just a cheery news item. Indeed it may offer a look at solar power’s future in the country.
CPV is of course Concentrating Photovoltaics. which in Mildura is getting solar cell efficiencies over 40%. No that was not a misprint. Forty Percent. Four Zero. Wowzers! Read that Wikipedia link to find out how they do it…
Here at SQHQ we’ve issued a number of rants (er discussion documents that is) on CPV and Mildura. These can be downloaded from the dank and dusty SQHQ archives shed here (second left past the outside dunny): [Read more…]
